ASSEMBLY Lubricating the thrust washers 1. After assembling the actuator but before putting it into service, the thrust washers must be coated with lithium grease. There are 2 greasing holes on each side of the shaft flange and the cap. They are sealed with assembly screws (113) and locking screws. Remove the screws from these greasing holes (see the exploded drawing on page 9).
ADVICE
Insert the nozzle of a grease gun in one of the holes and apply grease to the shaft flange. Continue to apply grease until it flows out of the opposite hole. Operate the actuator 5 times and then apply grease again. Repeat this procedure with the cap. Insert the 2 assembly screws in the greasing holes and tighten to a torque of 2.8 Nm (25 in-lb).
If a hydraulic test bench is not available, the actuator can be turned by hand; to do this, open the pressure holes and use a lever with the assembly screws inserted into the shaft clamp and turn the shaft in the desired direction.
